Reaction Steps

To a stirred mixture of 19 parts of 2-(methylthio)-1H-benzimidazole-1-propanol, 15.2 parts of N,N-diethylethanamine and 195 parts of dichloromethane are added dropwise 11.5 parts of methanesulfonyl chloride. Upon completion, stirring is continued for one hour at reflux. After cooling, water is added and the layers are separated. The organic phase is dried, filtered and evaporated, yielding 3-[2-(methylthio)-1H-benzimidazol-1-yl]propyl methanesulfonate as an oily residue.
